These are such self-evident considerations that it is useless to insist on them. Let us add that this duty rests, besides, on one of the most powerful instincts of humanity, the instinct of sympathy for other men, the horror of their sufferings, the horror of spilt blood. Those who are wanting in this sentiment are like monsters in the midst of humanity. One of the corollaries of this principle is to avoid the blows and wounds which might, through imprudence and unexpectedly, cause death, and which, besides, are in themselves to be condemned, inasmuch as they contribute, if not towards destroying, at least towards mutilating, the person and rendering it unfitted to fulfil its duties and functions. In a word, to avoid scuffles, bodily quarrels, which are unworthy, moreover, from their very brutality, of a reasonable being; all this is comprised in the duty of avoiding homicide. All may be summed up in these words of the Decalogue: "_Thou shalt not kill_." Pascal, in his letter on homicide (xiv. _Provinciale_), expressed most eloquently the duty concerning the respect for human life: "Everybody knows, my fathers, that individuals are never permitted to seek the death of any person, and that, even if a man should have ruined us, maimed us, burnt our houses, killed our parents, and was preparing to murder us, to rob us of our honor, that our seeking his death would not be listened to in a court of justice. So that it was necessary to establish public functionaries who seek it in the name of the king, or rather in the name of God. Suppose, then, these public functionaries should seek the death of him who has committed all these crimes, how would they proceed? Would they plunge the dagger in his breast at once? No; the life of man is too important; they would proceed with more consideration; the law has not left it subject to the decision of all sorts of people; but only to that of the judges, whose integrity and sufficiency have been ascertained. And think you that one alone is enough to condemn a man to death? No; there are at least seven required; and among these seven there must not be any one whom the criminal has in any way offended, for fear that his judgment be affected, or corrupted by anger. In short, they can judge him only upon the testimony of witnesses, and according to the other forms prescribed to them; in consequence of which they can conscientiously pronounce upon him only according to law, or judge worthy of death only those whom the law condemns." After having thus expounded the innumerable precautions which society has taken, out of respect for human life, touching the persons of criminals, Pascal continues as follows:
